On Friday, an unknown male entered the K-Mart at 1271 Hooksett Road around 6:16 p.m., police said. He exited the story around 6:41 p.m., and was seen lingering around the toy and electronics departments, police said.

While in the electronics department, he approached a female juvenile and tried to get her to watch a video on his cell phone.

Investigators said a person of interest was taken into custody Sunday but no other details were released.

Police said the man was in his late 20s or 30s, tall and has a thin build. He was wearing tight jeans, black boots that appear to be cowboy boots and a plaid short-sleeve shirt with the sleeves rolled up.

Officers said he has a neatly trimmed beard, with spiked, dark, short hair in the front. They believe he was wearing eye glasses.

Anyone who may have seen this male on Friday night or may have any information to help identify him are asked to call Sergeant Janet Bouchard at the Hooksett Police Department at 624-1560.
